Detailed Description
Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the various embodiments described. It will be apparent, however, to one skilled in the art that the various embodiments described may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail as not to unnecessarily obscure aspects of the embodiments.
Fig. 1 to 3 show an embodiment of an electromagnetic terminal shield, hereinafter referred to as shield 10, which is configured to be connected, for example, to a shield conductor of a shielded electrical cable (not shown) and to provide electromagnetic shielding to an electrical terminal (not shown) connected to an inner conductor of the shielded electrical cable. The shield 10 is configured to receive a corresponding mating electromagnetic terminal shield (not shown) therein. The shield 10 includes a shield body 12 formed from a flat metal plate, such as a tin-plated copper-based material. The shield body 12 has a connector opening 14 and a cable opening 16, the connector opening 14 being configured to receive a corresponding mating terminal shield, the cable opening 16 being configured to receive a shielded cable. The shielded cable preferably terminates in a sleeve (not shown) that is received within the cable opening 16. The shield 10 also includes a plurality of cantilevered spring arms 18 extending along the longitudinal axis X of the shield body 12, the plurality of cantilevered spring arms 18 being integrally formed with the shield body 12 and having a fixed end 20 attached to the connector opening 14 and a free end 22 disposed within a shield cavity 24 defined by the shield body 12.
As best shown in fig. 3, each spring arm 18 of the plurality of cantilevered spring arms 18 is curved within the shield cavity 24 toward an inner surface 26 of the shield body 12. The free end 22 of each spring arm 18 of the plurality of cantilevered spring arms 18 contacts an inner surface 26 of the shield body 12 within a shield cavity 24.
As best shown in fig. 1, the plurality of cantilevered spring arms 18 includes a first spring arm 18A, a second spring arm 18B that is generally parallel to the first spring arm 18A, and a third spring arm 18C that is generally parallel to the second spring arm 18B. The free ends 22 of the first, second and third spring arms 18A-18C are interconnected by a cross-bar 28, the cross-bar 28 contacting the inner surface 26 of the shield body 12 within the shield cavity 24.
As best shown in fig. 3, each spring arm 18 of the plurality of cantilevered spring arms 18 is opposite another spring arm 18 of the plurality of cantilevered spring arms 18.
As shown in fig. 1-3, the shield 10 further includes a longitudinal contact rib 30, the longitudinal contact rib 30 being molded out of the shield body 12 and protruding from the inner surface 26 into the shield cavity 24.
Fig. 4 shows the steps of a process 100 for manufacturing the above-described shield 10. The process 100 includes the following steps:
a terminal shield preform is formed 102 including forming a terminal shield preform from a flat metal plate having a plurality of elongated projections extending longitudinally from one end of the terminal shield preform. The green part may be cut from the sheet metal using stamping, die cutting, laser cutting, water jet cutting, or any other sheet metal cutting process known to those skilled in the art;
folding 104 the elongated projection toward the terminal shield preform includes folding the plurality of elongated projections toward the terminal shield preform to form a plurality of cantilevered spring arms 18. In the embodiment shown, the plurality of cantilevered spring arms 18 includes a first spring arm 18A, a second spring arm 18B that is generally parallel to the first spring arm 18A, and a third spring arm 18C that is generally parallel to the second spring arm 18B. The free ends 22 of the first, second and third spring arms 18A-18C are interconnected by a cross bar 28. Other embodiments may include a plurality of cantilevered spring arms 18 of different configurations.
Bending 106 each spring arm toward the inner surface is an optional step that includes folding a plurality of elongated projections toward the terminal shield preform to form a plurality of cantilevered spring arms 18. Step 106 is preferably performed before step 108; and
Spot welding the longitudinal seam joint 110 includes spot welding the longitudinal seam joint 34 of the shield body 12 adjacent the cable opening 16 of the shield body 12.
Accordingly, an electromagnetic terminal shield 10 and a process 100 for manufacturing the shield 10 are provided. The different spring rates of the first, second and third spring arms 18A-18C on either side of the shield 10 result in six independent and compliant points of contact between the shield 10 and the corresponding mating terminal shield. The shield 10 provides low engagement force but high normal contact force, thereby providing easy connection and high connection performance. Spring arms 18 contact shield body 12 at and near the front and back of shield body 12, providing improved flow of energy in shield 10 and optimal electromagnetic compatibility (EMC) performance.
When a mating electromagnetic terminal shield is engaged with the shield 10, the shield 10 provides three different spring rates. These three spring rates are provided by 1) cantilevered spring arms 18, 2) spring arms 18 that form a simply supported beam once the free ends 22 of the spring arms 18 engage the inner surface 26 of the shield body 12, and 3) the radial springs of the shield body 12 itself. As the mating electromagnetic terminal shield is inserted into the shield body 12, a first spring rate is provided as the free end 22 moves away from the inner surface of the shield 10 when the mating electromagnetic terminal shield is engaged with the spring arm 18. This provides a lower initial engagement force. When the free end 22 of the spring arm 18 engages the inner surface 26, the spring arm 18 becomes a simply supported beam, which provides a second spring rate. This will provide a higher normal force once the initial alignment is substantially complete and the engagement force is primarily caused by friction. The third spring rate is provided by the radial hoop shape of the shield 10 itself and the axial location of the spot welds 32 on the splice joint 34 of the shield body 12 near the cable opening 16. This allows for greater tolerances in the connector opening 14. The smaller the connector opening 14, the more interference is created with the mating electromagnetic terminal shield and results in a higher mating force. Before the mating force becomes too high, the shield body 12 will flex and the seam 34 will open instead.
The contact ribs 30 provide stability and improved normal force of the shield 10. Forming the spring arm 18 by folding the protrusion back into the shield cavity 24 of the shield body 12 eliminates the opening in the shield body 12, which improves EMC performance and increases contact protection.
